How to tell it

Branched rigid spines, and the whole plant covered in long white hairs, which separates it from all the gorses. Yellow flowers in tight spikes at branch tips. Hairy pods.

What it is confused with

Small-flowered gorse

Ulex parviflorus

Harmless confusion

Run a careful hand over it and look at the hairs: this is clearly hairy with branched spines; small-flowered gorse is smooth with simple spines. Both prick.

What it is for

Firewood and livestock bedding in the past. Today it counts as fire load and as ground cover on degraded slopes.
